Application filed .TulylO,

' This, invention relates to strainer and cover constructions forreceptacles. Although the invention is capable of use in connection withvarious types of containers, it is particularly adapted for use inconnection with milk pails, during the milking operation and during theprocess of treating the milk after the same has been taken from thecows.

It is anobject of this invention, therefore, to provide an improvedstrainer and cover for receptacles. 7

It is more specifically an object of this invention to provide such astrainer and cover which may be adjustable to fit receptacles ofdifferent sizes.

Still another object of the invention is to provide a strainer and acover adapted to lit the tops of varioussized pails having upwardlyflaring surfaces.

These and other objects of the invention will more fully appear from thefollowing description made in connection with the "accompanyingdrawings, wherein like characters refer to the same or similar partsthroughout the several views, and in which .-Fig. 1 is I applied to apail, a portion of the pail being broken away;

In the drawings, an upwardly flaring pail 6 of standard constructionis illustrated i having an outwardly extending roll 7 formed at itsupperend, a bales and ears 9 t0 Which the baleis se'curedf An arcuatelyshaped. strip 1O composed of flat resilient sheet material is providedhaving a plurality of spaced apertures l0 'shown as substantiallyhorizontally extending slots formed adjacent one end thereof and atongue 1O at its other end formed as shown cutting a slot partiallyacross the strip adjacent the end 10". Theupper edge of strip 10 has aroll 1O formed thereon extending from one end of the strip to withinashort distance from the other end thereof.

a perspective view of the device 1926. Serial No. 121,640. I

A stiffening rod 10 is secured in theroll 10 and projects outwardlytherefrom at one end and terminates short of the other end of the roll.An arcuate strip 11-, also composed from flat resilient sheet material,is provlded, having spaced apertures 11 adjacent one end, shown as beingsubstantially trans-- yerse slots, and a projecting tongue 11 at 1tsother end, the tongue 11 being shown as pro ecting longitudinally fromthe end of the strip 11. V

Strip l0 being of resilient material may be circularly bent as shown inFig. 1; the tongue 10 may be upwardly bent to the dotted position shownin Fig. 5, and the tongue engaged with any one of theapertures 10 theprojecting end of the stiffening rod 10 fitting within the opposite endof the roll 10 as the two ends of the strips are olned. It can beseenthat by placing the tongue 10 in the different apertures 10 thediameter of the band or ring formed by the strip 10 when the ends arejoined may be considerably varied. The two ends of the strip may berigidly secured together by bending the tongue 1 0 downwardly from thedotted position, as shown'in Fig. .5, to the position of thetongueshown, in full lines in Fig. 5. The ends of strip 10 having beenoined to form a band of suitable. diameter, the same may be'placed withits outer surface against the inner surface of a container or pailsuchas'the pail 6, the roll 10 of the band abutting the roll 7 of the pail,or if no roll or bead is provided on the pail, the roll l0 abutting thetop edge of the pail. Due to the, arcuate formation of the strip 10, asthe ends of the same are joined to form a band, the band will be givenan upwardly flaring shape so that the whole outer surface of the bandwill contact the inner surface of the pail adjacent the top thereof. Thestrip 10 will form the outer band of the strainer and cover. i

The ends of the strip 11 may now be joined bycurving" the strip to forma rough circle and inserting the tongue 11 in one of the apertures 11the outer diameter of the inner band so formed being made by properadjustment of the tongue 11 in the aper-, tures 11 to approximatelyequal the inner diameter of the outer band 10.- The ends of the stripllInlay be secured by bending the tongue 1 1 touthe dotted position shownin Fig. 4e, inserting the tongue in one of the apertures 11 andreversely bending the material is placed to extend somewhat below theouter band 10 with portions thereof contacting the sides of the band atall pointson its lower inner circumference The inner band 11 may now beinserted within the.

outline of the outer band 10 on top of the portions of the flexiblesheet member 12 which cont-act'the inner surfaces of the outer band, andthe co operating inner surface of the outer band and theouter surface ofthe inner band will securely clamp the straining member 12 in operativeposition.'

The band 11 being formed from an arcuate strip will have upwardlyflaring surfaces so that the outer sides of the band will closelyconform to the inner surface ofthejouter band. The strainer and covermay be assembled before or after the outer band is positioned onereceptacle or pail, but is preferably assembled before the outer band isseated on the receptacle.

If desired, either or both of the tongues 10' and 11 instead of beingfirst outwardly bent from the main body portions of the bands as theends of the two bands are joined, may be inwardly bent. The, ends of thebands will then be joined at opposite sides thereof from the joinedsides shown in the drawings. The position of tongue 10 adjacent the endof the band 10 may be varied if desired. Various types of aperturesandjton ues may be formed on the strips 10 and 11 fi when the ends ofthe strips may be secured together. 7 i 3 Thefdevice when applied to apail will provide a strainer which can be used at the time a cow ismilked to strain the milk and keep all sediment falling from the cowsandotherwisev blowing about from falling into the milk. If the milk fromthe cow is bloody or gargety, this will be indicated on the strainermember. The quality of'the milk will accordingly be increased by use ofthepresent invention. as sediment that would otherwise fall into thepail wouldd1ssolt e to a. certain extent in the milk and the value ofthe milk would accordingly be decreased. There will be no opportunityfor the milker' to get his hands into the pail while the cows are beingmilked, and accordingly drier and cleanli'er milking will beaccomplished. The

strainer and. coverwill notget in the way ofthe milking operation.

Preferably cheesecloth is used for the straining member 1 2 and thiscloth can be readily removed for cleaning b simply dissemblingt-he twobands 10 an 11 an 7 ing the straining member 12 from theouter bandwhereupon the same may be readily washed. If wire mesh is used for thestrainthevsame has been run through a separator.

This cooling process is usually accomplished by allowing the pails ofmilk to stand in .cold water for some length of time and allowing milkto be exposed to the airto take out all the animal heat frorn the milk.With the present device the pails 'may be 0on veniently placed in waterandthe device will provide a cover over the pails which will prevent themilk from becoming fouled and yet will permit the access of air to themilk.

The device will alsohavehigh utility for use in other connectionsthaninmilking or in treating milk. l

It will, ofcours'e, be. understood that various changes may be made inthe form, details, arrangements and proportions of the various partswithout departing from'the scope of the present invention which, generally stated, consists in the matter shown and described and set forthin the following claims.
